Behaviour of superconductivity energetic characteristics in electron-doped cuprates. A simple model [PDF]

, 2007
A simple model to describe the energetic phase diagram of electron-doped cuprate superconductor is developed. Interband pairing operates between the UHB and the defect states created by doping and supplied by both extincting HB-s.
